Ashlee, 28, showed off her lean, toned body in a tiny string bikini while playing on the beach with son Bronx, 4, and a pal on Saturday, Dec. 29 in Hawaii. The mother-and-son duo held hands as they splashed around in the water together and soaked up the sun.

Jessica, who is expecting her second child with fiance Eric Johnson, tried to hide her baby bump while serving as maid of honor in the ceremony. The Fashion Star mentor, 32, finally confirmed her pregnancy on Christmas Day by sharing a photo of daughter Maxwell, nearly 8 months, sitting on the beach with "Big Sis" written in the sand.

Johnson, 33, was photographed going for a bike ride with the Scrubs actor Saturday, but the second-time mom-to-be apparently didn't tag along.

The pair, engaged since November 2010, recently put an offer on a house in Hidden Hills, California, for their growing family. And the NFL pro is also settling into domesticity. "He is amazing with Max," a source told Us Weekly. "Eric tells Jessica he has everything he's ever wanted."
